What structural features give a large stokes shift?
Best insight from top research papers
The structural features that give a large Stokes shift include the presence of fused rings and the ability to easily functionalize the carbon core . Additionally, the formation of stable complexes with different ligands is another key feature that contributes to a large Stokes shift . In the case of RNA-chromophore complexes, the formation of a G-quadruplex upon ligand binding is observed, which is responsible for the large Stokes shift and strong fluorescence enhancement . Furthermore, the design of caging-group-free photoactivatable dyes with red fluorescence emission and ∼100 nm Stokes shifts is achieved through a 1-vinyl-10-silaxanthone imine core structure . In the case of Sb2S3 materials, the presence of sulfide vacancy-bound excitons leads to a large Stokes shift, which can rationalize the experimental observations of a reduction in open circuit voltage .

How to design a structure?10 answersDesigning a structure involves a comprehensive process that integrates various methodologies and technologies to ensure the stability, strength, and rigidity of the structure to withstand all applied loads without failure during its intended life. The initial step in structural design involves generating a set of candidate designs through an optimization process, where each design comprises a set of design variables associated with a multidimensional design space. This is followed by selecting a subset of these designs for further analysis.
Modern structural design emphasizes not only the physical integrity of the structure but also its operational functions, necessitating a holistic approach that starts from the subsystem and considers the structure as a whole. This approach is particularly relevant in the context of additive manufacturing technology, which allows for the creation of complex structural geometries and metamaterials tailored to specific patient-oriented medical applications.
The design process also involves the use of computer-implemented systems that facilitate the coordination of design implementation, optimization of the design for various criteria, and quantification of various attributes of the structure. Additionally, the design method may incorporate the analysis of design performance for specific components, such as vibration damping members in aerospace applications, to ensure that the structure meets required performance standards.
Furthermore, the design process can benefit from multi-scale simulation operations to achieve an optimum design that balances multiple kinds of performance in a trade-off relationship. The use of a computer to calculate structure data and create a basic frame of the structure from a basic shape further exemplifies the integration of technology in structural design.
Finally, ensuring that the structure or building complies with applicable standards for load combinations and control values is crucial. This involves a system that uses a database to store numerical values corresponding to design parameters, allowing for updates and modifications to be made efficiently.
What is the structural characteristics of BRPF1?5 answersBRPF1, a core subunit of the MORF acetyltransferase complex, exhibits unique structural features. It contains a PZP domain composed of a PHD finger, a zinc knuckle, and another PHD finger, enabling interactions with histone H3 tails and DNA. Additionally, BRPF1 is part of the BRPF1-KAT6A/KAT6B complex, which plays crucial roles in various biological processes and is associated with neurodevelopmental disorders, leukemia, and other cancers. The BRPF1 bromodomain specifically recognizes di-acetyllysine modifications on histone H4, preferentially binding to peptides like H4K5acK8ac and H4K5acK12ac, shedding light on how post-translational modifications influence its chromatin recruitment. This selective binding is coordinated by the bromodomain's monomeric state and involves specific amino acids near the canonical binding pocket, highlighting the importance of combinatorial modifications in regulating BRPF1 interactions with chromatin.
What is the anatomical structure of the eye?5 answersThe anatomical structure of the eye is complex and can be divided into two main segments: the anterior segment and the posterior segment. The anterior segment includes the cornea, conjunctiva, iris, ciliary body, anterior and posterior chambers, and the lens. The cornea is the transparent membrane at the front of the eye, which continues as the sclera. The conjunctiva is a mucous membrane that covers the inner surface of the eyelids and the visible part of the sclera. The posterior segment includes the retina, which is responsible for the first step in neural processing of an image and transmitting it to the brain. The eye is a unique organ with specific physiological functions and disease conditions associated with each segment.
What is the best structure to hold a heavy weight?5 answersThe best structure to hold a heavy weight depends on the specific requirements and context. One option is a heavy equipment counter weight structure, which can be used to control the balance of loads and prevent accidents during movement. Another option is a mounting structure of a counter weight for heavy equipment, which maintains a uniform distance between the counter weight and the equipment frame to prevent interference. A structure for bearing weight with support posts, beams, joists, and retaining means can also be effective. Additionally, a hook structure with link chains and metal bulkheads can distribute tensile forces in a massive cubic structure of concrete. For stationary, level mounting of heavy objects, a support structure with a flat top and sidewalls, supported by an outwardly extending flange, can be used. Each of these structures offers unique advantages depending on the specific application.
What is the structure of caffeine?4 answersCaffeine is a secondary metabolite produced by certain plant species and is a key component of coffee and tea. The structure of caffeine consists of a purine base skeleton, with partial charges, that allows for molecular interactions in aqueous solution. The crystal structure of caffeine has been determined in various studies. One study found that caffeine crystallizes in the orthorhombic space group P212121 with specific unit cell dimensions. Another study described the crystal structure of a complex containing caffeine, which consists of centrosymmetric dimeric units with zinc atoms coordinated by bridging benzoates and caffeine ligands. These studies provide insights into the molecular structure and arrangement of caffeine in different contexts.
What is structures of heart?5 answersThe major structural parts of the heart include the muscular wall (myocardium), the inner lining (endothelium), the outer lining (pericardium), and the blood vessels supplying the heart with blood. The heart is a thoracic musculocavitary, intrapericardial organ, situated in the middle mediastinum. It is a heterogeneous, complex helical structure with asymmetric and anisotropic features, consisting of spiraling muscle bands, valves, coronary vessels, and a conduction system. The heart is divided into four chambers, with the upper chambers called the right and left atrium, and the lower chambers called the right and left ventricles. The heart functions as a pump to circulate blood containing oxygen, glucose, protein, fat, and salts to every organ, tissue, and living cell of the body.
